How fast do new technologies grow? This question seems simple but is not.
Growth is not linear: it is initially irregular, then exponential, then stabilises before slowing down.
In a new @NatureJnrl paper we develop new metrics to describe this path. 1/17 go.nature.com/2VFOjoT Why is this important?
To understand which climate targets are reachable we need to know whether renewables can grow fast enough.

Here I break down the methodological advances which we're super excited about. 2/17

We know how to save the climate in mathematical models but is it possible in the real world? @acherp & I propose a new method to explore feasibility of climate mitigation @WIREs_Reviews bit.ly/2rsBfE1, a sequel to my exchange w/ @KevinClimate go.nature.com/2qE2zie. /1 An outcome is politically feasible if there are agents who can carry out a set of actions to realise it in a given context. Therefore analysis of political feasibility means asking 3 questions: “feasibility of what?”, “feasibility when and where?” and “feasibility for whom?” /2
